SPECIFICATION forming part of Letters Patent No 381,793. dated April 24, 1888.

Application filed March 15, 1887. Serial No 230.953. tNb model.)

To all whom, it may concern:

Be it known that I, WILLIAM J. KEEP, of Detroit, in the county of \Vayuc and State of Michigan, have invented new and useful Improvements in Cooking-Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in cooking-stoves, and is more especial y designed to be employed in the class of stoves that are provided with revertible flues.

The invention consists'in the peculiar combinations and the novel construction,arrangement, and adaptation of parts, all as more fully hereinafter described, and then particularly pointed out in the claims- Figure 1 is a sectional perspective view of the rear portion of a stove, showing position of damper and rod when closed. Fig. 2 is a sectional plan of lines, showing damper open to direct draft. Fig. 3 isa cross-section looking to the rear with damper closed. Fig. 4 is a vertical section. Fig. 5 is a detail perspec tive of damper and rod.

In the accompanying drawings, which form a part of this specification, A represents a stove, the space between the back plate, B, of the oven and the back plate, 0, of the stove being divided into the'central direct-draft flue, a, and the downflues b by the flue-strips c d, these flues communicating with flues below the oven, as in the ordinary manner.

D is the top plate of the oven. Upon referring to Fig. 4 it will be seen that the rear portion of this top plate dips downwardly to the top of the bacleoven-plate, B. This construction is to provide a greater area at the entrance to theflues a b.

.In the flue-strip 0 there is formed a vertical groove or channel, 6, to receive the vertical damper-rod E, the lower end of which is stepped in a suitable socket or bearing, f,

rect draft, in which case the groove ecould be dispensed with.

F is the damper, which is pivotally secured between the walls of the flue, so as to close or 5 disclose the direct draft tine. This damper I preferably construct in two parts, the main portion being provided with a journal area, i, a downwardlyprojecting spur, j, and a leverarm, 70. To the opposite lower corner of the damper F is removably secured a plate, G, carrying a journal-arm, Z. The twojournalarmsi Z, when the damper is in place, find hearings in the flue-walls c d.

H is a cam arm or horn projecting laterally from the damper rod E, and this arm H lies :underneath the arm k of the damper and against the spnrj.

The upper edges of the side plates of the stove in which the oven-doors arelocated flare outwardly, forming extension-fines m, and are so formed to enlarge the entrance to the dues b. The depression ordip to the rear edge of the oven top plate above described, together with the extension fines m, increases the entrance to the flues fully equal to the area of the exit-collar over the direct-draft due. The parts being in place,it will readily be seen that by turning the damper-handle to the rear the rod is caused to partially rotate. The arm H 8:) thereof, pushing against the spur j, compels the damper to open or assume a horizontal position, thus opening thepassage for direct draft.

In a retrograde movement of the damper-rod the canrarm H, in its action upon the leverarm is, compels the damper to assume its closed position, thus directing the products of combustion to the down orflside lines.

By constructing the damper in two parts I am enabled to put it into position after the go stove is put together, and to remove it without disturbing any other part of the stove.

It will be observed that the damper-rod, being partially concealed in the groove of the flue strip, is not liable to be affected by the 5 'flames in direct draft, and, being in a vertical position, the oven-doors can he made larger than if the dam per-rod projects horizontally,

I in which latter case the doors would have to be made smaller in order that they might open and not interfere with the damper.

While I have shown and described a stove provided with two downflues, it is evident that my invention could be advantageously embodied in stoves wherein provision is made for but two fluesone direct and one revertible or down flue.

I have spoken of one descending and one ascending fine separated by a strip. It is not necessary that in all cases this strip shall be a thin piece of iron. It may be desirable to separate the does from each other a farther distance than it would be necessary to bound each fine by a separate wall; but the operation would be the same in either case.

In the top of the back plate, B, of the oven is formed a recess, a, to receive the horn H of the damper-rod, and this allows me to locate such dampenrod in close proximity to the hack oven-plate.

On top of the stove,in front of the hand1e,is a stop, 0, which acts as a guard to prevent articles placed on the stove from accidentally opening the damper.

What I claim as my invention is- 1. A cooking stove having an oven and a fine extending over the oven-top and from side to side of the stove, and downdraft-fines and a central updraft-flue between said downdraftfines, the top plate of the oven being depressed at its rear edge, whereby the size of the opening between the flue over the oven and the central-draft flue is increased, substantially as described.

2. The combination, with a stove provided with a directdraft fine and two downflues, of a pivoted dropping-damper arranged to control the exit of the direct-draft flue, and avertical damper-rod for said damper, turning on its axis at right angles to the movement of said damper, substantially as and for the purpose specified.

3. The combination, with astove having two or more rear vertical flues and a grooved strip forming a division-wall between said fiues, of avertical damper-rod situated in said groove, and a damper actuated by said rod, substantially as described.

4. The combination, with a stove having two or more rear vertical flues and aflue-wall having a lip, of avertical damper-rod concealed by said lip and a damper actuated by said rod substantially as described.

5. The combination, with a stove, of a vertical flue, a damper closing the entrance to said flue, and a vertically-grooved fluestrip provided at its lower end with a socket, and a vertical dam per-rod stepped in said socket and situated in said groove, substantially as de' scribed.

6. The combination, with a stove provided with a back plate and a back oven-plate arranged with a space between them, of a damper arranged within said space and provided with spur j and arm is, and a vertical dampenrod, E, provided with a laterally-projecting cam arm or horn, H, working between said spur and arm, substantially as and for the purposes set forth.

7. The combination, with a stove having an oven, of a flue in the rear thereof, a damper closing the entrance to said flue, a plate forming one wall of said flue and provided with a recess, a, and a damper-rod having a horn working in said recess, substantially as described.
